SHOE-FASTENING.

SPECIFICATION forming part of Letters Patent No. 228,946, dated June 15,1880.

Application filed March 1, 1880. (ModeL) Patented in Germany September26, 1879.

To all whom it may concern:

Be it known that we, FRIEDRICH SoHULz and AUGUST SOHULZ, residents ofBerlin, in the Kingdom of Prussia, German Empire, and doing businessunder the firm ofFR. 85 AUG. SOHULZ, have invented new and usefulImprovements in Shoe-Locks, of which the foL lowing is a specification.

Our invention relates to improvements in buckles or devices forfastening shoes, applicable also to wearingapparel, and has for itsobject to avoid the usual mode of lacing and to provide for im mediatetightening or connecting two parts of a garment.

In the accompanying drawings, Figure l is an under-side view, showingthe fastening device open. Fig. 2 is-a like view, showing it closed, andFig. 3 is a detail View.

A represents a carrier or button, of any preferred or desired shape andmaterial. It is provided with two studs or pins at points equidistantfrom its center, upon which are. pivoted two curved arms, B, with theircurved portions facing in opposite directions. The outer end of the armsB is enlarged to form a bearing provided with slots 1), and said outerends are sewed to the opposite ends or edges of the shoe-vamp in such amanner that when the fastening device is in the position shown in Fig. 1the foot may be readily slipped into the shoe. If the button or carrierA is now rotated the arms B, at their pivoted end, are swung arounduntil the curved parts I) of said arms are interlocked one with theother, as shown in Fig. 2, and the opposite edges of the leather drawntogether.

Owing to the fact that the arms B, when in the position shown in Fig. 2,have passed the (lead-points of their respective fnlcra, any

strain upon said arms will only tend to lock them more firmly together,and they cannot be released except by rotating or turning the carrier orbutton in a reverse direction.

The arms may be made of any suitable material. In practice I stamp themout of thin flexible sheet metal, especially when employed on shoes, sothat the said arms may readily adapt themselves to the shape of theinstep of the foot or other part thereof.

WVhen the device is employed upon garments one of the latches or arms Bonly is sewed or otherwise permanently connected to one part thereof,the adjacent part being provided with the hook O, which, when the twoparts of the garment are to be fastened or connected together, is hookedin the arm B that is free, and when it is desired to bring said parts ofthe garment closer together the button or carrier A is rotated,as beforedescribed.

Having now described our invention, what we claim is- 1. The combinationof the carrier A, carryin g the pivots a at points equidistant from itscenter, with the curved arms B, provided with slots I), substantially asshown and described, and operating as set forth.

2. The combination of the carrier A and its pivoted curved and slottedarms B with the hook 0, all constructed and operating as set forth.

In witness that we claim the foregoing we have hereunto set our handsthis 23d day of January, 1880.
